Drivers will have to travel further to get a new driving licence as of next week and will no longer be able to ask a relative to get it for them.
That's because a new system of issuing and renewing licences will start next Tuesday with a much smaller network of offices than at present.
There will be 34 centres for renewing licences and issuing learner permits, compared to the current network of 55 motor tax offices which will cease issuing licences after Friday.
A large county such as Donegal, which has six offices for licence renewals, will see that cut to two, while Limerick will have just one, compared to three at present.
People will no longer be able to get a relative to apply for them because under the strict new security system, customers have to apply face-to-face and have their photo taken at the centre.
The Irish Postmasters' Union (IPU) said thousands of Irish drivers were being seriously inconvenienced by the move, with the elderly most affected.
IPU president Ciaran McEntee said there would be a huge amount of driving in larger counties such as Cork and Mayo, adding: "Elderly drivers have to renew their licences more frequently, thus increasing travel time and inconvenience."
The new National Driver Licence Service (NDLS) is being rolled out by the Department of Transport, Tourism and Sport as part of the move to plastic card licences and learner permits.
"The locations of the centres have been chosen to ensure 95pc of the population is serviced within a 50km radius of a centre," the NDLS said on its website.
Centres will remain open during lunchtime, with opening hours 9am-5pm, Monday to Friday, and 9am-2pm on Saturday.
The Dublin offices will be in Leopardstown, Citywest and Santry instead of Dublin 7, Clondalkin and Ballymun at present.
There are no changes to licence fees – currently €55 for a 10-year one, €35 for three years and €25 for one year, with a learner permit costing €35. Licences for over-70s are free.
The NDLS said the new application process was designed to "increase the level of security around the driving licence, combat fraud and keep unlicensed drivers off our roads by ensuring that the only person who will use your licence is you".
